Hi sorry to bother you, but I just read your post about that very negative person’s tags and you say that Sam and Dean have separate heavens. Would you mind clarifying that a little bit? Because it always seemed to me that they shared the same heaven, just different memories in that heaven and Ash had to break them out of it to bring them to his heaven. But maybe I interpreted it wrong…

thevioletcaptain:

It’s no bother at all, nonny! Below is a quick breakdown of things we were shown in Dark Side of the Moon;

1. There are an infinite number of separate mini-Heavens within Heaven and each is constructed around the best memories of the individual or set of soul mates it is meant for.
2. These different Heavens are connected by the Axis Mundi, which appears differently to everyone, but once a person knows how to travel along it they are able to move between their own Heaven and those of other people they seek out.
3. For Dean, the Axis Mundi is a literal road. Ash is shown using sigils he’s learned by “hacking” heaven with complex equations and a home-made computer to travel.
4. The memories relived in the episode are these:

   – Dean setting off fireworks with a young Sam on the 4th of July, ‘96 (Dean’s memory)

   – Sam eating Thanksgiving dinner with the family of a girl he had a crush on as a kid (Sam’s memory)
   
   – Dean’s bedroom when he was around four years old, and then spending time with Mary (Dean’s memory)

   -Sam’s dog Bones in the apartment where he spent two weeks living away from John and Dean after running away (Sam’s memory)

   -The night Sam left for Stanford (Sam’s memory)

5. We can tell whose memory each is in two main ways. First, the person remembering appears their current age in the memory, regardless of how old they were when it happened, and second, they are the only one capable of interacting with the memory.
6. Dean says multiple times during the episode that Sam’s best memories are some of his worst.

For Sam and Dean to share a heaven or be soul mates as some people believe them to be, they would have to share the same happy memories. It couldn’t have been made clearer that this wasn’t the case when Dean flat out says this:

“This is your idea of heaven? Wow. This was one of the worst nights of my life.”

Other people have already discussed all of this at length–in particular, @ceeainthereforthat​ wrote a great essay on the topic–so I’ll direct you to that for further reading on that episode, but I will just add that in Angel Heart last season, we saw what a shared Heaven looked like when Amelia arrived to find Jimmy immediately. She didn’t need to go searching for him.
